Abstract (en)

[origin: EP3422187A1] The present disclosure relates to a signal processing device, a signal processing method, and a program that enable detection of a failure without stopping signal processing. A toggle rate is calculated for each of signals of a preceding stage and a subsequent stage of a signal processing unit and, in a case where a difference therebetween is larger than a predetermined threshold value, it is assumed that an error caused by a failure is occurring in the signal processing unit. The present disclosure can be applied to a drive assistance device of a vehicle.
